The IBM 2741 Terminal

The IBM 2741 was a Selectric typewriter embedded in a small-desk-size cabinet
crammed with electronics and wire bundles, communicating at 134.5 bits
per second, half duplex. When it was the computer's turn to transmit, it
physically locked the keyboard. The print element (not visible in this photo)
resembled a golf ball, and was replaceable with other Selectric balls --
italics, APL, and so on. Date: About 1965.
